Run Up to 33-Inch Tires with Confidence: Gain the clearance you need to conquer rough terrain. This kit includes durable lifted knuckles and strut spacers, providing room for larger tires while maintaining optimal geometry. Engineered for a Factory-Like Ride: Precision-designed differential drop brackets, sway-bar brackets, brake line extensions, and a driveshaft spacer work together to maintain proper angles, ensuring a smooth, controlled ride, even with added lift. Heavy-Duty Crossmembers Built to Last: Front and rear crossmembers are reinforced for maximum strength and feature a modern design tailored to fit newer F-150 models seamlessly.

Stronger, Longer-Lasting Rear Blocks: Fabricated rear blocks are engineered to outperform and outlast cast alternatives, delivering enhanced durability in demanding conditions. Ride Quality You Control: Fully Configurable with Shock/Strut Options: Choose from nitrogen-charged N3 shocks for balanced performance, or upgrade to M1 Monotube shocks for enhanced ride precision and heat dissipation. Built-In Anti-Axle Wrap Design: Specially designed rear blocks combat axle wrap and eliminate common lift block issues, all while preserving the factory ride feel. Peace of Mind Included: Rough Country backs this kit with a Limited Lifetime Replacement Guarantee, ensuring your suspension is ready for whatever comes next.
